CharisFlew with TAP AIR PORTUGAL-Apr 2026
Make sure your luggage is plastic wrapped if you’re flying in rain!
SnapyouFlew with easyJet-Apr 2026
easyJet is pretty good for low cost carrier. Because of the way the terminal is structured, there is a much longer walk and more stairs than would be expected. My favourite airport is LHR, and I prefer LGW over LTN, but LTN is closer to home.
Verified travelerFlew with British Airways-Jun 2024
Try the business class option as not much more expensive. You get three seats for two people, good food, drinks and more leg room plus priority boarding.

Tivat airport was really terrible, but the flight was excellent

Kayak told me in the morning that the 16.40 flight would be late! It arrived late to pick us up and arrived at Manchester 35 minutes late. We then had to wait quite a while for the luggage to come through. Missed our train because of this!

Apart from the 3 hour delay, the flight was fine. The seats could have been a little more comfortable, but the staff were great! The seats are not as functional - removing the place to put your book / tablet is a real inconvenience. The food choices could be a little more varied / healthy.

Meals could improve Very plain and poor quality. I wouldn't mind payın more for better.

Seat spacing good ( I am tall), very friendly and competent cabin crew. Good updates from flight deck. Excellent boarding and disembarcation

Crew was nice. Plane was crowded, Seats wouldn’t lean back. No free treats or drinks (not even water).

They are organised and customer service is so good from arriving at the airport until finally landing at your destination. The experience is a million times better than travel with Ryanair.

The plane was late in so we were late leaving. The plane had been cleaned and was tidy, the staff were welcoming. Our standard seat had good legroom but after an hour or so of sitting, the Seat started to feel uncomfortable. We didn’t have any food so can’t comment on that and there was no entertainment available. We did buy some duty-free goods and the prices are good. We made up the lost time and landed slightly early.

Boarding time was confusing. On boarding ticket it said 2:50 but then the board said boarding now from 2:20. In the end people were still boarding at 3:00 so it meant people were sitting on the plane for 40 mins. Staff were very friendly from check in to plane to arrival. Plane was fine for the type of journey. Food was adequate and good selection.

Flight was late, and not sure why. The business class lounge in Porto is not proprietary to TAP, and is really substandard, almost as bad as "The Lounge" in Boston. It was a D, which is better than the F experience in Bostonm where we left "The Lounge" for a better experience in the terminal. It had better food (an extremely low bar), ok beverages, and wasn't as crowded as the Boston one, but no restrooms. To use one, you had to leave and go downstairs. There's no down escalator, and the elevator might be able to crowd 4 people. Otherwise, you're carying your bags down the stairs. I hope the Lisbon club is better, but for TAP to provide this in the 2nd largest city in the home country is disappointing. They put out an announcement to proceed immediately to the gate, but there was no plane and few seats. from the lounge, 8 people with bags waited in line for the single tiny elevator. After almost an hour of standing, we finally boarded. TAP, at least on this plane, doesn't offer a welcome drink to business class passengers. Having said that, the crew was very friendly and accomodating. We landed about an hour late and then were told we were going to be on the runway for at least a half hour because no gate was available. So, bottom line, D- for pre boarding, A for flight attendents, B + for business class food, and Incomplete for post landing.

Let’s be honest. You know you are boarding a flight where the seats don’t recline and you need to pay double the price for bread, gin and water. But beware, they test your tolerance to torture pre boarding. They call all British passport holders. Then tag cabin luggage to be checked. And the ground staff pretend not to know what is happening and just says - please ask the other staff.

It poured rain, our luggage was sitting out in it uncovered on the transport cart while our plane was delayed! Nice business class plane for short flight to Lisbon, but more delay & rain in Lisbon, with terrible Business class seat with no entertainment & cold food on longer flight to London…ALL LUGGAGE AND CLOTHES INSIDE THEM WERE SOAKED THROUGH!!! Could only try with hair dryer to get some drying before quick turn round to train trip.

Menzies group staff not very sympathetic good at breaking up families during the boarding process

There was no warning that they have added passport control after check in, the line was enormous and after 46 mins wait we missed our flight. Were forced to leave the airport and purchase new tickets at full price to board a later flight. TAP were unsympathetic and unhelpful.

Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.

Not much to like. Check-in and bag drop procedures are a crowded, disorganized and confusing mess. Agents were grumpy and unhelpful, somehow expecting passengers to automatically know and understand the airline's procedures. Boarding was chaotic and included a stand-up, sardine-packed bus ride to a stairway pushed up to the aircraft out on the tarmac. Passengers were left waiting in the bus for a lengthy period on both ends. Flight departure and arrival were delayed by passengers scrambling to find space for bags in the overhead storage. Many passengers not in compliance with carry-on rules. Everything you could hate about flying in this ride.

Its a short flight with no entertainment. The food was so so.

Dreadful - queued to get onto a bus, stood for 10 minutes on the bus, drove to the plane, stood for another 25 minutes on the bus outside the plane. When allowed on we could only board from the front & were seated in the furthest row back. The second bus was allowed to board from the back so chaos ensued!. The flight was an hour late - nobody said why, nobody apologised. On arrival at Heathrow we stood for nearly 30 minutes before being allowed off - again with no explanation,

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

On time! The wait to board standing outside was miserable. The “priority” boarding is misleading as it does not help the boarding process at all. The bag charges were very high and my expected carry on did not quite fit in the measurement box. The lobby experience at the airport was terrible! Signage and directions were inadequate. The staff was all lovely.

Sadly the experience with the airline is worse one ever. Starting from the state of the inside that was filthy that flies was flying around our legs. The food is expensive than a restaurant, imagine a family of 4 spending almost £50 for just sandwich of bread and ham no tomatoes and lettuce in it and a small container of crips that is not up to 20 pieces and a can of coke or Pepsi, and unfortunately that is a person ffour hours pay of work before tax. I know the blame will go to high cost of living but even at that the price is too much.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

Good flight. Take off a little late but make up the time

I didn't like. The seats and the floor were very dirty and it is not the first time

The workers checking passengers from the boarding gate stole money from people whose luggage was perfectly fitting inside the carry-on sizer.

Whole way through - far more professional and slick than I expected

Good news was that Bag Check was open two and a half hours before the flight, which is essential with the chaotic immigration process. Flight was okay, but sitting at the back of the aircraft, 3 overhead bins on both sides were filled with crew bags and other misc items, so we couldn't put our cabin bags anywhere near us. To add insult, twice the crew managed to drop items that they were taking out of the overhead bins onto my wife's head, who was sitting in an aisle seat.

You need to make signage at Berlin Airport clearer. Having checked in online we had our boarding passes onlour phones. You do not make it clear that you need to check in again to receive a printed luggage tag. You get to baggage drop off and it says you can only do it with a luggage tag BUT not how to get this.

It was good except they could offer free water and tea/coffe

Sat at rear of aircraft and was very cold. As a frequent flyer for many years, this is was the coldest I have ever been. Other passengers and some crew were complaining how cold it was. Sitting near the doors always risks being colder, just the way the aircraft works - but this was exceptional, bring a good jumper. Everything else was pretty standard easyJet - good value low cost carrier.

The plane was postponed for over 2.5 hours, which meant that all four of us missed the check in time for our ongoing trip to Melbourne. We had to buy new tickets for 4 people as we had to forfeit the ones we had. The cost was really unfair. i understand that it was snowing during the first leg of the plane for that morning. Surely the cost could have been shared by the airline and not all by us. I could have bought insurance - but you can see how much I travel. I will need to chose more trustworthy airlines.

The true is that travel from London to Faro on 11/12/2025 by BA was cancelled, so I did not go to Faro, so i did not board easy flight. The mediocre qualification to you was because even when i bought an insurance, i could not change date neither obtain reimbursement. It could be ideal if you do something in order for me not to lose the purchase Thank you

Queuing for quite a while despite using the "speedy boarding".

The flight boarded a little late but made up the time in flight - much appreciated. The staff were efficient and fairly friendly One of the toilets wasn’t working - having only one functioning toilet for a flight of hundreds isn’t really acceptable. I still find it amazing that the budget airlines can’t even offer free tap water to passengers.

Over sold! Never again. Got bumped even though I checked in and arrived on time with all my documents in order. Wasn’t even offer food/drink voucher for the next flight that was 6 hours later.

First time flying with them! Loved it! Specially the schedule from Miami and being able to come back directly to New Orleans :)

The boarding was a mess as there was another document check in the small congested area after the stairs at the gate. No food is offered for Economy travelers except for a cookie and a small water bottle. No entertainment is available since it’s a short flight. But at least the seat reclined as opposed to my flight to Faro.

The transit at Heathrow was an absolute and total nightmare. Absolutely gut wrenchingly horrible and scary. Embarrassing that their National air carrier cannot figure a half decent experience for passengers to transit via London. Shameful.

I do not understand how BA takes coach seating and has people paying for business class. There is no leg room, seats don’t recline and no entertainment to be had unless you brought your own.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.

The flight was fine but they made me pay for my carryon bag because they said it was too big at the counter. But it fit under the seat just fine.

Outdated from start to finish. Good was inedible, choice was very poor. They don’t seem to care

I never got the flight. Someone hacked your information and sold me a fake flight. Didn't know this till I tried to check in and was told the flight didn't exsist and it was a fraudulent ticket. I'm not sure how to get this fixed but I had to pay $1500 to book a last minute flight. I understand that this was not Kayak company that sold me a fake flight but I was sold a fake flight based on my booking with Kayak. I ended up having to pay for an extra night hotel stay. I guess I need to start by contacting someone at kayak to get this resolved. My bank has stopped all bank transactions because of it.

Every flight was delayed. They lost our luggage for days.
